- Circular cloud, the rotating mesocyclone of a supercell
- W912410S
- A dark base extends to the right away from the rain. Under it, a circular cloud represents the rotating mesocyclone of this supercell. Even lower down is a lighter, low attached cloud which is the storm's wall cloud. Outflow has stretched it to the right side of the circulation where the updraft finally gains control of it to allow the air to rise and condense.
